摘要
多年來，可編程控制器（以下簡稱PLC）從其產(chǎn)生到現(xiàn)在，實(shí)現(xiàn)了接線邏輯到存儲邏輯的飛躍；其功能從弱到強(qiáng)，實(shí)現(xiàn)了邏輯控制到數(shù)字控制的進(jìn)步；其應(yīng)用領(lǐng)域從小到大，實(shí)現(xiàn)了單體設(shè)備簡單控制到勝任運(yùn)動控制、過程控制及集散控制等各種任務(wù)的跨越。今天的PLC在處理模擬量、數(shù)字運(yùn)算、人機(jī)接口和網(wǎng)絡(luò)的各方面能力都已大幅提高，成為工業(yè)控制領(lǐng)域的主流控制設(shè)備，在各行各業(yè)發(fā)揮著越來越大的作用。
本文介紹了PLC的現(xiàn)狀，以及與其他控制系統(tǒng)有什么區(qū)別，如何對PLC，伺服等進(jìn)行進(jìn)行選型.設(shè)計(jì)出基于三菱FX2N-32MR以及配套三菱FX2N-1PG定位模塊，三菱MR-J3-20A伺服系統(tǒng)以及光柵等組成的自動焊接系統(tǒng)，。系統(tǒng)可以根據(jù)不同要求，改動焊接參數(shù)，從而達(dá)到不同的目的。本設(shè)計(jì)還采用了觸摸屏作為人機(jī)界面，通過觸摸屏的操作可進(jìn)行參數(shù)設(shè)置，實(shí)現(xiàn)對各種功能的控制，同時(shí)還能通過觸摸屏顯示測試結(jié)果和對系統(tǒng)當(dāng)前運(yùn)行狀態(tài)進(jìn)行實(shí)時(shí)的監(jiān)控。

Abstract
Over these years， the programmable logic controller (PLC) have realized the some developements when plc has beed produced. It turned the logical connection to the storage logical connection， and its function from weak to strong， and the result is realizing the progress of the logic control to digital control. it applicats in some airas， from small to big. it realizes the using of simple equipment in achieving a single control to do motion control， process control and distributed control across a variety of tasks. Today， PLC has been in dealing with analog and digital computing， human-machine interfaces and network capabilities ，and has became the mainstream of the field of industrial controls and control equipment. Overall， it has play an increasingly important role in all walks of life .
This article describes the presedent status of the PLC， as well as with other What is the difference between control system， how to PLC， servo， etc. Designed  the automatic welding systemsthe which composed by Mitsubishi FX2N-32MR-based as well as ancillary Mitsubishi FX2N-1PG positioning module. This System can be designed with different requirements， such as change in experimental parameters so as to achieving different purposes. The design also uses a touch screen as a man-machine interface through the touch-screen operation parameters， which can be set up to achieve the control of various functions， but also through the touch screen display the test results and the status of currently running on the system for real-time monitoring.

Key words: Automatic welding system，PLC，touch screen，Positioning Module
